The iDRIVE throttle controller gives you complete control over the responsiveness of your vehicle. It does this by providing new points of reference for your throttle mapping, introducing either a sharper or duller throttle curve depending on what mode/setting has been selected.
Economy mode reduces the throttle response passed factory levels, the higher you set the iDRIVE the more dampened your throttle response becomes. Economy mode is perfectly suited to off-road and low traction driving situations; by dampening your throttle response and having a more controlled application of power to your wheels you can significantly improve your vehicles traction capabilities. Economy mode is also great for low speed towing situations where you don't want to be constantly jerking on the throttle and overcorrecting your steering.
Ultimate performance mode increases your throttle response, the higher you set the iDRIVE the more aggressive your throttle response becomes. Ultimate Mode has 9 settings and can be grouped into three stages. Ultimate mode 1-3: Everyday driving with smooth acceleration. Ultimate mode 4-6: Sportier, more responsive acceleration, great for use around town where short bursts of acceleration are needed. Ultimate mode 7-9: Strap yourself in and activate launch control, instant throttle response, beast mode, don’t say we didn’t warn you.
Automatic control mode automatically selects your vehicles throttle response based on your current driving style. If you are in traffic and accelerating gently the iDRIVE will automatically choose a reduced level of throttle response such as Economy Mode 2. However if you accelerate hard to overtake or power up a hill, the iDRIVE will choose a far more aggressive throttle response for you such as Ultimate Mode 7. The iDRIVE adapts to how you're currently driving and delivers the best throttle response to match. Automatic Control mode is what makes the iDRIVE one of the most intelligent throttle controllers on the market.
